Virtual Wind Tunnel: Gurney Flap

These are the results of a CFD "virtual wind tunnel" simulation of a Kyosho Mini-Z MR03 Mazda 787b 3D model with a 4 mm gurney flap.

The drag force recorded by the simulation while the car was "racing" at 10 m/s (36 km/h) was 7.2 gf. The down force recorded by the simulation at this speed was 5.7 gf.

The pictures below show the pressure coefficient (Cp) indicating high (red) and low (blue) pressure areas.
